Entrainment of Stage 2 Sleep Spindles by Weak, Transcerebral Magnetic Stimulation in an “Epileptic” Woman
Bibliographic record
Abstract
The proportions of Stage 2 spindles present per second over the prefrontal and temporal lobes of a patient who had been experiencing complex partial epileptic-like experiences and disturbances in sleep patterns for four years following a closed head injury were measured while a weak (1 microT) burst-firing magnetic field was applied transcerebrally through the temporoparietal regions. In several successive segments during the exposure the onsets of the spindles were significantly correlated (rhos between 0.30 and 0.40) with the onset of the field that was presented once every 3 s for about 0.7 s. Lag/lead analyses indicated only the contemporary occurrence of the fields and the spindles were significantly correlated over time. These results suggest that some states of consciousness, particularly those associated with the "epilepsy spectrum disorder" may be more sensitive to entrainment or "synchronization" by weak complex magnetic fields whose temporal structures are designed to simulate natural brain activity.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
